Hi, i am the developer of xorriso, which created the image in question under control of the debian-cd package.
Debian i386 images are ISO 9660 filesystems with El Torito Boot Record to boot from CD/DVD/BD, and with Master Boot Record, which enables them to boot from hard disk and USB stick. If you put an ISO 9660 image onto the overall device file of an USB stick (e.g. /dev/sdb) then it should be mountable by the overall device file of the stick, too: dd if=debian-7.3.0-i386-netinst.iso of=/dev/sdb mkdir /mnt/my_debian_7_1 mount -t iso9660 /dev/sdb /mnt/my_debian_7_1 To then see all its files, do find /mnt/my_debian_7_1 Some technical background: El Torito and MBR are only present for pointing BIOS to the boot files which it shall execute to bring up an operating system. The MBR might have a confusing impact on programs which inspect devices and try to be smart. A program which simply complies to the specs of ISO 9660, El Torito, and MBR should have no problem. The El Torito stuff already was shown here by the output of isoinfo. The MBR can be made visible by a run of fdisk on the .iso file /sbin/fdisk -lu debian-7.3.0-i386-netinst.iso or if already on USB stick /dev/sdb, by /sbin/fdisk -lu /dev/sdb which should yield: Device Boot Start End Blocks Id System /dev/sdb1 * 64 567295 283616 17 Hidden HPFS/NTFS This means that there is a MBR partition 1 with some filesystem. (The System type is prescribed by the ISOLINUX project.) By a special preparation of the ISO image, it should be possible to mount it as superuser by the partition device file, too: mount -t iso9660 /dev/sdb1 /mnt/my_debian_7_1 The reason why both device files /dev/sdb and /dev/sdb1 work for mounting is that the ISO has two superblocks and directory trees. One pair ready for mounting from /dev/sdb and for mounting from CD/DVD/BD. The other pair is ready for mounting /dev/sdb1.
